Defects recorded against failed normal tests, 2005–2025, grouped by DVSA inspection section. One test can record multiple defects. "vs all bikes" is how often this model's tests record a defect in the group, as a multiple of the all-bike rate.

How rivals compare

same type, similar capacity, high test volume

On first-time pass rate the GSX650 beats 3 of its 4 closest rivals (KAWASAKI ZX-6R, SUZUKI GSF600, YAMAHA FZS600).

Rivals share this bike's type and sit within ±30% of its engine capacity, ≥ 5,000 tests. Card colour = better/worse first-time pass rate than the GSX650.

Pass rate by registration year

how each model-year cohort fares · registration year from first use date

Best year to buy used: 2011 (91.5% pass). Weakest: 2009 (85.7%).

First-time pass rate by the year each bike was first registered (cohorts with ≥ 50 tests). Older cohorts are survivors: the worst examples have already left the road, which tends to lift the earliest years.

SUZUKI GSX650 FAQ

answers computed from the data above · terms in the glossary

Is the SUZUKI GSX650 reliable?

The SUZUKI GSX650 is about average for its class: 86.5% of its 1,694 MOT tests (2005–2025) passed first time, against a class average of 84.9%. That ranks it #2050 of 5426 models.

What does a GSX650 fail its MOT on most?

brakes — 28% of all defects recorded against failed GSX650 tests.

What is the best year of GSX650 to buy used?

By first-time pass rate, 2011-registered examples do best (91.5%) and 2009 worst (85.7%). Condition and history still trump the year.

How many miles will a GSX650 last?

The median GSX650 shows 13,011 miles at test, and examples around 40k miles still pass 76.2% of the time — mileage alone rarely kills one.
